TONGUE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 702,291, dated June 10,1902. Application iiled April 5, 1902. Serial No. 101,457. (No model.)

To @ZZ whom it may concern."

Be it known that I, SAMUEL EBEnsoLn, a citizen of the United States,residing at Clearspring, in the county of Washington and State ofMaryland, have invented new and useful Improvements in Tongue-Supports,of which the following is a specification.

My invention relates to poles for vehicles, harvesters, dto.; and theobject of the same is to construct a hinged pole or tongue which will beprovided with a support located intermediate its ends and bearing on theground, the outer end of which tongue will always remain at the sameheight no matter how much the tongue is inclined.

My invention therefore overcomes the wellknown difficulty which arisesin using tongues having a central support which bears on the ground.

The novel construction employed by me in carrying out my inventionisfully described in this specification and claimed, and illustrated inthe accompanying drawings, forming a part thereof, in which- Figure 1 isa side elevation of a tongue equipped with my device and in its normalposition. Fig. 2 is a side elevation with the tongue in its abnormalinclined position. Fig. 3 is a detail section of the lowerend of theguides. Fig. 4 is a horizontal section of the same.

Like numerals of reference designate like parts in the diderent views ofthe drawings.

The numeral 1 designates a tongue hinged to the front part 2 of avehicle, harvester, dac. Connected to the tongue 1 at a point near themiddle is a spring-arm 3, which is attached by means of a bolt 4,slidingly mounted in guides 5, secured to the tongue. A spring 6surrounds the bolt 4 and bears at one end on the guides 5 and at theother on the head 4 of the bolt 4. l y

The spring-arm 3 bears a plate 7 on its free end. Pivotally secured tothe plate 7 is a caster-wheel 8, located to run on the ground andsupport the tongue 1. Also carried by the arm 3 are two parallelguide-arms 9, which extend upwardly and embrace the tongue 1. The lowerends 9L of the guides 9 are bent at right angles and have slots 9btherein through which bolts 10 pass to secure the guides to the plate 7.By this arrangement the distance between the guides 9 can be regulatedand adapted for tongues of different sizes.

Perforations 1l are formed in the guides 9 and located oppositely inpairs. A cross-pin 12 passes through two of the perforations and issurrounded by a cylinder 13, bearing an ear 13, having'an aperture 13btherein. Lugs 13c on the ear form stops to limit the movement thereof. Abolt 14 passes through the aperture 13b and bears a nut lwhich serves toconfine a spiral spring 16, which surrounds the bolt 14 and bears on theear 13a. The nut 15Ud also serves to adjust the tension of the spring16.

One arm 17 a of an elbow-lever 17 is connected to the lower end of thebolt 14,and the other arm 17b is attached to a connecting-rod 18; TheAelbow-lever 17 is fulcrumed in a standard 19, mounted on the tongue 1 inthe rear of the guides 9. The upper end of the connecting-rodlS is'pivoted on apintle 20, which extends through an aperture 21a in alever-arm 22, fulcrumed at its lower end in a standard 23, mounted onthe tongue 1. An elbow-lever 24 hasits short arm 24a connected to theupper end of the lever-arm 22 and is fulcrumed on a standard 25, mountedon the front 2 of the machine.

Normally thetongue 1 extends almost horizontally, as shown in Fig. 1,the caster-wheel 8 supports the weight thereof, and the springarm 3 willtake up the vibration caused by passingover rough ground. y If themachine 2, to which the tongue is attached, be a harvester which it isdesired to incline to cut low stubbles, the lever 24 is thrown into theposition shown in Fig. 2, when the tongue will assume an inclinedposition; but the forward end or tip will stand at the same height asbefore, owing to the action of the spring-arm 3 on the connectingmechanism, which permits the rear end of the tongue to lower withoutchanging the position of the tip.

I do not wish to be limited as to details of construction, as these maybe modified in many particulars without departing from the spirit of myinvention.

Having described my invention, what I IOO claim as new, and desire tosecure by Letters Patent, is

l. The combination With a hinged tongue, of a bolt slidingly mounted inguides carried by said tongue, a spring mounted to yieldingly hold saidbolt, a spring-arm connected to said bolt, guides carried by saidspringarm and embracing said tongue and a caster- Wheel carried by saidarm and located to run on the ground to support said tongue,substantially as described.

2. The combination with a hinged tongue, of a spring-arm connected tosaid tongue a caster-Wheel carried by the free end of said arm, guidescarried by said arm and embracing said tongue, an apertured ear mountedon said guides, a pin slidingly mounted in said aperture, a springyieldingly holding said pin against longitudinal movement, a levermounted on said pole, and pivoted to said pin, and means for operatingsaid lever.

3. The combination with a hinged tongue, of a spring-arm connected tosaid tongue, a caster-wheel carried by the free end of said arm, guidesmounted on said arm and embracing said tongue, a cross-pin connectingsaid guides, an elbow-lever mounted in a standard supported by saidtongue, one arm 0f said lever being connected to said crosspin, andmeans for operating the other arm of said elbow-lever to incline saidtongue, substantially as described.

4. The combination with a hinged tongue, of a spring-arm connected tosaid tongue, a caster-Wheel carried by the free end of said arm, guidescarried by said arm and embracing said tongue, a lever mounted on saidtongue and having one arm connected to said guides, a standard pivotedto said tongue, a lever fulcrumed on the body of the Wagon and havingone arm connected to said standard, and a connecting-rod connecting saidstandard and the other arm of said lever, substantially as described.

5. The combination with a hinged tongue, of guides embracing saidtongue, means for yieldingly holding said guides against movement, acaster-Wheel carried by said guides and located to bear on the ground, alever carried by said tongue and having one arm connected to saidguides, and means for operating the other arm of said lever,substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
